Hello,
I have a question regarding electrical testing please. I have a transformer charger that the spade connections have come out on the transformer power supply end. The plug is a european two pin that is sealed so I cannot see the wiring at the plug end. At the charger end I have a spade connection marked L and the other is of course the neutral / return. I am obviously not an electrician and would like to know if there is no colour coding on the cables how can i test to see which of the feed wires should be plugged into the live ??
Secondly, on three phase wiring with only an earth and not a neutral, how do you test for voltage?? Is it possible to put the voltmeter probes in to any two of the phases and get a reading? That makes sense to me, but I have not done it before so am a little nervous. I currently work on a yacht that has three phase generators and shore power and have much to learn quickly!!
And finally, can anyone recommend a good electrical testing and training school around the hampshire area.
Kind regards,
Simon
